6.3.1 Changing Setting of I/O Terminals (Parallel I/O)
Set the minimum OFF time of READ END signal and ACCEPT signal. And also, assign functions to
ASSIGN0-5 when operating by inputting signals to I/O connector and I/O terminals ASSIGN0-5 from the
external device.
See chapter 8: Operation and Data Output through I/O Terminals, page 359.
1
. Select "Parallel I/O" in the input/output setting window.
The parallel setting window is displayed.
2.
Specify “REND OFF Min.” and “ACCEPT OFF Min.”
Settable Range: 0 (default) to 1000
Set these items when external devices such as a PLC cannot detect signal switch between ON and OFF
because the OFF time of READ END signal and ACCEPT signal is too short.
3
. In “Set Signal ASSIGN0” to “Set Signal ASSIGN5”, assign functions as needed.
Default assignment setting
ASSIGN0: Template Setting
ASSIGN1: Switch RUN/STOP
ASSIGN2: Save Data in PV
ASSIGN3: Save Data in SD
ASSIGN4: Read Data from PV
ASSIGN5: Read Data from SD
4
. After setting is completed, press the CANCEL key.
6.3.2 Changing Communication Condition of COM.0 port (Serial)
This is a setting of the COM.0 port for RS-232C communication. Specify the setting values to the same as that
for the external device to communicate.
Item Option Description
Baud Rate
(bps) 1200/ 2400/ 4800/ 9600/ 19200/
38400/ 57600/ 115200 (Default
setting: 9600) Transmission speed for communication. The
higher number the faster communication speed.
Bit Length 7 / 8 (Default setting: 8) To set the bit number per letter.
Stop Bit 1 / 2 (Default setting: 1) To set the bit number of the signal that recognizes
the end of data.
Parity Check None/ Odd/ Even (Default setting:
Odd) To set the number of overhead bits to check for
proper data transmission.
Flow Control None/Soft Flow/ Hard Flow
(Default setting: None) To set how to control the handshake flow.
•
When "Destination" is "Serial (COM.0)", the communication condition is changed to each default
values if switching "Protocol" (General purpose communication, PLC communication) or changing
PLC type. If the protocol or PLC type was changed by mistake, check the serial communication
conditions again.
•
When "Protocol" is "PLC Communication" and "PLC Type" is "Mitsubishi: MELSEC-FX" or "Fuji:
MICREX-SX", the communication condition is fixed and cannot be changed according to that of
the destination PLC.
